2011-03-28fs,ocfs2: Move o2net_get_func_run_time under CONFIG_OCFS2_FS_STATS.Rakib Mullick1-5/+5
When CONFIG_DEBUG_FS=y and CONFIG_OCFS2_FS_STATS=n, we get the following warning: fs/ocfs2/cluster/tcp.c:213:16: warning: ‘o2net_get_func_run_time’ defined but not used Since o2net_get_func_run_time is only called from o2net_update_recv_stats, so move it under CONFIG_OCFS2_FS_STATS.

2011-02-22ocfs2/dlm: Move kmalloc() outside the spinlockSunil Mushran1-12/+16

2011-02-21ocfs2: Little refactoring against ocfs2_iget.Tao Ma1-5/+5
ocfs2_iget is used to get/create inode. Only iget5_locked will give us an inode = NULL. So move this check ahead of ocfs2_read_locked_inode so that we don't need to check inode before we read and unlock inode. This is also helpful for trace event(see the next patch).

As there are no such debug information in fs/ocfs2/ioctl.c, fs/ocfs2/locks.c and fs/ocfs2/sysfile.c, ML_INODE are also removed. Signed-off-by: Tao Ma <[email protected]>

2011-02-22ocfs2: Remove DISK_ALLOC from masklog.Tao Ma6-6/+0
Since all 4 files, localalloc.c, suballoc.c, alloc.c and resize.c, which use DISK_ALLOC are changed to trace events, Remove masklog DISK_ALLOC totally. Signed-off-by: Tao Ma <[email protected]>
2011-02-22ocfs2: Remove mlog(0) from fs/ocfs2/suballoc.cTao Ma2-5/+17

2011-02-22ocfs2: Remove mlog(0) from fs/ocfs2/localalloc.cTao Ma2-34/+135
This is the 2nd step to remove the debug info of DISK_ALLOC. So this patch removes all mlog(0,...) from localalloc.c and adds the corresponding tracepoints. Different mlogs have different solutions. 1. Some are replaced with trace event directly. 2. Some are replaced while some new parameters are added. 3. Some are combined into one trace events. 4. Some redundant mlogs are removed. Signed-off-by: Tao Ma <[email protected]>
2011-02-22ocfs2: Remove mlog(0) from fs/ocfs2/alloc.cTao Ma2-77/+452
This is the first try of replacing debug mlog(0,...) to trace events. Wengang has did some work in his original patch http://oss.oracle.com/pipermail/ocfs2-devel/2009-November/005513.html But he didn't finished it. So this patch removes all mlog(0,...) from alloc.c and adds the corresponding trace events. Different mlogs have different solutions. 1. Some are replaced with trace event directly. 2. Some are replaced and some new parameters are added since I think we need to know the btree owner in that case. 3. Some are combined into one trace events. 4. Some redundant mlogs are removed. What's more, it defines some event classes so that we can use them later. Cc: Wengang Wang <[email protected]> Signed-off-by: Tao Ma <[email protected]>
2011-02-21ocfs2: Add ocfs2_trace.h.Wengang Wang2-0/+19
About one year ago, Wengang Wang tried some first steps to add tracepoints to ocfs2. Hiss original patch is here: http://oss.oracle.com/pipermail/ocfs2-devel/2009-November/005512.html But as Steven Rostedt indicated in his article http://lwn.net/Articles/383362/, we'd better have our trace files resides in fs/ocfs2, so I rewrited the patch using the method Steven mentioned in that article.

2011-03-07ocfs2: Remove EXIT from masklog.Tao Ma27-315/+159
mlog_exit is used to record the exit status of a function. But because it is added in so many functions, if we enable it, the system logs get filled up quickly and cause too much I/O. So actually no one can open it for a production system or even for a test. This patch just try to remove it or change it. So: 1. if all the error paths already use mlog_errno, it is just removed. Otherwise, it will be replaced by mlog_errno. 2. if it is used to print some return value, it is replaced with mlog(0,...). mlog_exit_ptr is changed to mlog(0. All those mlog(0,...) will be replaced with trace events later. Signed-off-by: Tao Ma <[email protected]>
2011-02-21ocfs2: Remove ENTRY from masklog.Tao Ma31-418/+161
ENTRY is used to record the entry of a function. But because it is added in so many functions, if we enable it, the system logs get filled up quickly and cause too much I/O. So actually no one can open it for a production system or even for a test. So for mlog_entry_void, we just remove it. for mlog_entry(...), we replace it with mlog(0,...), and they will be replace by trace event later. Signed-off-by: Tao Ma <[email protected]>

2011-03-15VFS: Fix the nfs sillyrename regression in kernel 2.6.38Trond Myklebust1-1/+6
The new vfs locking scheme introduced in 2.6.38 breaks NFS sillyrename because the latter relies on being able to determine the parent directory of the dentry in the ->iput() callback in order to send the appropriate unlink rpc call. Looking at the code that cares about races with dput(), there doesn't seem to be anything that specifically uses d_parent as a test for whether or not there is a race: - __d_lookup_rcu(), __d_lookup() all test for d_hashed() after d_parent - shrink_dcache_for_umount() is safe since nothing else can rearrange the dentries in that super block. - have_submount(), select_parent() and d_genocide() can test for a deletion if we set the DCACHE_DISCONNECTED flag when the dentry is removed from the parent's d_subdirs list.

2011-03-15dcache.c: create helper function for duplicated functionalityLinus Torvalds1-51/+37
This creates a helper function for he "try to ascend into the parent directory" case, which was written out in triplicate before. With all the locking and subtle sequence number stuff, we really don't want to duplicate that kind of code. Signed-off-by: Linus Torvalds <[email protected]>
2011-03-15tidy the trailing symlinks traversal upAl Viro1-45/+26
* pull the handling of current->total_link_count into __do_follow_link() * put the common "do ->put_link() if needed and path_put() the link" stuff into a helper (put_link(nd, link, cookie)) * rename __do_follow_link() to follow_link(), while we are at it Signed-off-by: Al Viro <[email protected]>
2011-03-15Turn resolution of trailing symlinks iterative everywhereAl Viro1-54/+50
The last remaining place (resolution of nested symlink) converted to the loop of the same kind we have in path_lookupat() and path_openat(). Note that we still *do* have a recursion in pathname resolution; can't avoid it, really. However, it's strictly for nested symlinks now - i.e. ones in the middle of a pathname. link_path_walk() has lost the tail now - it always walks everything except the last component. do_follow_link() renamed to nested_symlink() and moved down. Signed-off-by: Al Viro <[email protected]>
2011-03-15simplify link_path_walk() tailAl Viro1-7/+1
Now that link_path_walk() is called without LOOKUP_PARENT only from do_follow_link(), we can simplify the checks in last component handling. First of all, checking if we'd arrived to a directory is not needed - the caller will check it anyway. And LOOKUP_FOLLOW is guaranteed to be there, since we only get to that place with nd->depth > 0. Signed-off-by: Al Viro <[email protected]>
2011-03-15Make trailing symlink resolution in path_lookupat() iterativeAl Viro1-10/+53
Now the only caller of link_path_walk() that does *not* pass LOOKUP_PARENT is do_follow_link() Signed-off-by: Al Viro <[email protected]>

2011-03-15pull handling of one pathname component into a helperAl Viro1-68/+55
new helper: walk_component(). Handles everything except symlinks; returns negative on error, 0 on success and 1 on symlinks we decided to follow. Drops out of RCU mode on such symlinks. link_path_walk() and do_last() switched to using that. Signed-off-by: Al Viro <[email protected]>
