Cleanup handling of S_NOQUOTA inode flag and document it a bit. The flag does not have to be set under dqptr_sem. Only functions modifying inode's dquot pointers have to check the flag under dqptr_sem before going forward with the modification. This way we are sure that we cannot add new dquot pointers to the inode which is just becoming a quota file. The good thing about this cleanup is that there are no more places in quota code which enforce i_mutex vs. dqptr_sem lock ordering (in particular that dqptr_sem -> i_mutex of quota file). This should silence some (false) lockdep warnings with ext4 + quota and generally make life of some filesystems easier. Signed-off-by: Jan Kara <jack@suse.cz> |
