From 28ca489c63e9aceed8801d2f82d731b3c9aa50f5 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Mon, 20 May 2013 09:51:09 +1000 Subject: xfs: fix rounding in xfs_free_file_space The offset passed into xfs_free_file_space() needs to be rounded down to a certain size, but the rounding mask is built by a 32 bit variable. Hence the mask will always mask off the upper 32 bits of the offset and lead to incorrect writeback and invalidation ranges. This is not actually exposed as a bug because we writeback and invalidate from the rounded offset to the end of the file, and hence the offset we are actually punching a hole out of will always be covered by the code. This needs fixing, however, if we ever want to use exact ranges for writeback/invalidation here...

Add project quota changes to all the places where group quota field is used: * add separate project quota members into various structures * split project quota and group quotas so that instead of overriding the group quota members incore, the new project quota members are used instead * get rid of usage of the OQUOTA flag incore, in favor of separate group and project quota flags. * add a project dquot argument to various functions. Not using the pquotino field from superblock yet.
