https://bugzilla.kernel.org/show_bug.cgi?id=15792 --- Comment #4 from Dmitry Monakhov <dmonakhov@xxxxxxxxxx> 2010-04-15 22:52:22 --- Most interesting part is last lines [61] [2] truncate clr s:737987 d:737987 b:104 fl:80000 [62] [0] clr ext4_inode_blocks_set b:104 fl:480000 bit:40000 [63] [2] trunc_ext begin s:737987 d:737987 b:104 fl:480000 ml:1 I.E. CPU2: is doing EXT4_I(inode)->i_flags &= ~EXT4_EOFBLOCKS_FL CPU0: is doung ei->i_flags &= ~EXT4_HUGE_FILE_FL CPU2: Wow EXT4_EOFBLOCKS_FL appear again due to race with cpu0. So even if truncate holds i_mutex it is possible to modify i_flags. Seems that we have to modify i_flags via anomic bits operations. A fix is almost ready. Currently i'm testing it. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
