Revision 330fe3c4c6509e0418c434b5bcf80e65cffab477 authored by Artem Bityutskiy on 31 May 2012, 23:26:12 UTC, committed by Linus Torvalds on 01 June 2012, 00:49:28 UTC
Preparation for further changes. It touches few functions in fatent.c and prevents them from marking the superblock as dirty unnecessarily often. Namely, instead of marking it as dirty in the internal tight loops - do it only once at the end of the functions. And instead of marking it as dirty while holding the FAT table lock, do it outside the lock. The reason for this patch is that marking the superblock as dirty will soon become a little bit heavier operation, so it is cleaner to do this only when it is necessary.
