[PATCH 08/13] ext4: simplify i_state checks in __ext4_update_other_inode_time()

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

 



From: Eric Biggers <ebiggers@xxxxxxxxxx>

Since I_DIRTY_TIME and I_DIRTY_INODE are mutually exclusive in i_state,
there's no need to check for I_DIRTY_TIME && !I_DIRTY_INODE.  Just check
for I_DIRTY_TIME.
