[PATCH V4 01/13] fs/xfs: Remove unnecessary initialization of i_rwsem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ira Weiny <ira.weiny@xxxxxxxxx>

xfs_reinit_inode() -> inode_init_always() already handles calling
init_rwsem(i_rwsem).  Doing so again is unneeded.

Signed-off-by: Ira Weiny <ira.weiny@xxxxxxxxx>

New for V4:

NOTE: This was found while ensuring the new i_aops_sem was properly
handled.  It seems like this is a layering violation so I think it is
worth cleaning up so as to not confuse others.
