[PATCH] Ext2/3 noatime and dirsync fixes
Patch from "Theodore Ts'o" <tytso@mit.edu>
I recently noticed a bug in ext2/3; newly created inodes which inherit
the noatime flag from their containing directory do not respect noatime
until the inode is flushed from the inode cache and then re-read later.
This is because the code which checks the ext2 no-atime attribute and
then sets the S_NOATIME in inode->i_flags is present in
ext2_read_inode(), but not in ext2_new_inode().
I fixed this in 2.4, and then found an even worse bug in the 2.5 code;
the DIRSYNC flag is completely ignored *except* in the case where a
directory is newly created using mkdir and its parent directory has the
DIRSYNC flag. S_DIRSYNC doesn't get set in the ext2_new_inode() or the
ext2_ioctl() paths (which is used by chattr).
This patch centralizes the code which translates the ext2 flags in the
raw ext2 inode to the appropriate flag values in inode->i_flags in a
single location. This fixes the bug, makes things cleaner, and also
removes 30 lines of code and 128 bytes of compiled x86 text in the
bargain.
