  "message": "quota: Cleanup S_NOQUOTA handling\n\nCleanup handling of S_NOQUOTA inode flag and document it a bit. The flag\ndoes not have to be set under dqptr_sem. Only functions modifying inode\u0027s\ndquot pointers have to check the flag under dqptr_sem before going forward\nwith the modification. This way we are sure that we cannot add new dquot\npointers to the inode which is just becoming a quota file.\n\nThe good thing about this cleanup is that there are no more places in quota\ncode which enforce i_mutex vs. dqptr_sem lock ordering (in particular that\ndqptr_sem -\u003e i_mutex of quota file). This should silence some (false) lockdep\nwarnings with ext4 + quota and generally make life of some filesystems easier.\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n",
