commit 0ac6c98294d666762960824d39329459b22b48b7
Author: Mikhail Gusarov <dottedmag@xxxxxxxxxxxxx>
Date: Mon May 28 14:52:21 2012 +0900
Fix cache aging for fonts on FAT filesystem under Linux
Windows does not update mtime of directory on FAT filesystem when
file is added to it or removed from it. Fontconfig uses mtime of
directory to check cache file aging and hence fails to detect
newly added or recently removed files.
This changeset detects FAT filesystem (currently implemented for
Linux) and adds generating checksum of directory entries instead
of using mtime which guarantees proper cache rebuild.
For non-FAT filesystems this patch adds single syscall per directory
which is negligeable overhead.
This fixes bug https://bugs.freedesktop.org/show_bug.cgi?id=25535

commit 6a83c1ad40594530994b826d928312e9eeb19c35
Author: Mikhail Gusarov <dottedmag@xxxxxxxxxxxxx>

Move FcStat to separate compilation unit
FcStat() logic is quite complicated in presence of various semi-broken operating
systems and filesystems, split it out in order to make it a bit easier.
