2018-01-17xfs: cross-reference the realtime bitmapDarrick J. Wong1-0/+4
While we're scrubbing various btrees, cross-reference the records with the other metadata. Signed-off-by: Darrick J. Wong <[email protected]> Reviewed-by: Dave Chinner <[email protected]>
2017-10-26xfs: create block pointer check functionsDarrick J. Wong1-0/+2
Create some helper functions to check that a block pointer points within the filesystem (or AG) and doesn't point at static metadata. We will use this for scrub. Signed-off-by: Darrick J. Wong <[email protected]> Reviewed-by: Dave Chinner <[email protected]>
2017-06-19xfs: export various function for the online scrubberDarrick J. Wong1-0/+3
Export various internal functions so that the online scrubber can use them to check the state of metadata. Signed-off-by: Darrick J. Wong <[email protected]> Reviewed-by: Brian Foster <[email protected]>
2017-04-03xfs: add a couple of queries to iterate free extents in the rtbitmapDarrick J. Wong1-2/+20
Add _query_range and _query_all functions to the realtime bitmap allocator. These two functions are similar in usage to the btree functions with the same name and will be used for getfsmap and scrub. Signed-off-by: Darrick J. Wong <[email protected]> Reviewed-by: Brian Foster <[email protected]>
2017-02-17xfs: simplify xfs_rtallocate_extentChristoph Hellwig1-2/+1
We can deduce the allocation type from the bno argument, and do the return without prod much simpler internally. Signed-off-by: Christoph Hellwig <[email protected]> Reviewed-by: Darrick J.

2016-06-01xfs: make several functions staticEric Sandeen1-2/+0
Al Viro noticed that xfs_lock_inodes should be static, and that led to ... a few more. These are just the easy ones, others require moving functions higher in source files, so that's not done here to keep this review simple.

2014-09-09xfs: combine xfs_rtmodify_summary and xfs_rtget_summaryEric Sandeen1-0/+4
xfs_rtmodify_summary and xfs_rtget_summary are almost identical; fold them into xfs_rtmodify_summary_int(), with wrappers for each of the original calls. The _int function modifies if a delta is passed, and returns a summary pointer if *sum is passed.

2014-06-25xfs: global error sign conversionDave Chinner1-1/+1
Convert all the errors the core XFs code to negative error signs like the rest of the kernel and remove all the sign conversion we do in the interface layers. Errors for conversion (and comparison) found via searches like: $ git grep " E" fs/xfs $ git grep "return E" fs/xfs $ git grep " E[A-Z].*;$" fs/xfs Negation points found via searches like: $ git grep "= -[a-z,A-Z]" fs/xfs $ git grep "return -[a-z,A-D,F-Z]" fs/xfs $ git grep " -[a-z].*;" fs/xfs [ with some bits I missed from Brian Foster ] Signed-off-by: Dave Chinner <[email protected]> Reviewed-by: Brian Foster <[email protected]> Signed-off-by: Dave Chinner <[email protected]>
2013-10-23xfs: split xfs_rtalloc.c for userspace sanityDave Chinner1-0/+24
xfs_rtalloc.c is partially shared with userspace. Split the file up into two parts - one that is kernel private and the other which is wholly shared with userspace.

2013-08-12xfs: introduce xfs_rtalloc_defs.hDave Chinner1-51/+2
There are quite a few realtime device definitions shared with userspace. Move them from xfs_rtalloc.h to xfs_rt_alloc_defs.h so we don't need to share xfs_rtalloc.h with userspace anymore.

2010-05-28xfs: be more explicit if RT mount fails due to configEric Sandeen1-1/+10
Recent testers were slightly confused that a realtime mount failed due to missing CONFIG_XFS_RT; we can make that a little more obvious.

2009-02-04xfs: make sure to free the real-time inodes in the mount error pathChristoph Hellwig1-0/+4
When mount fails after allocating the real-time inodes we currently leak them. Add a new helper to free the real-time inodes which can be used by both the mount and unmount path. Signed-off-by: Christoph Hellwig <[email protected]> Reviewed-by: Felix Blyakher <[email protected]>
2008-02-07[XFS] optimize XFS_IS_REALTIME_INODE w/o realtime configEric Sandeen1-2/+0
Use XFS_IS_REALTIME_INODE in more places, and #define it to 0 if CONFIG_XFS_RT is off. This should be safe because mount checks in xfs_rtmount_init: so if we get mounted w/o CONFIG_XFS_RT, no realtime inodes should be encountered after that. Defining XFS_IS_REALTIME_INODE to 0 saves a bit of stack space, presumeably gcc can optimize around the various "if (0)" type checks: xfs_alloc_file_space -8 xfs_bmap_adjacent -16 xfs_bmapi -8 xfs_bmap_rtalloc -16 xfs_bunmapi -28 xfs_free_file_space -64 xfs_imap +8 <-- ? hmm. xfs_iomap_write_direct -12 xfs_qm_dqusage_adjust -4 xfs_qm_vop_chown_reserve -4 SGI-PV: 971186 SGI-Modid: xfs-linux-melb:xfs-kern:30014a Signed-off-by: Eric Sandeen <[email protected]> Signed-off-by: David Chinner <[email protected]> Signed-off-by: Lachlan McIlroy <[email protected]>

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+187
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
