The patch titled fuse: fix attributes after open(O_TRUNC) has been removed from the -mm tree. Its filename was fuse-fix-attributes-after-openo_trunc.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: fuse: fix attributes after open(O_TRUNC) From: Ken Sumrall <ksumrall@xxxxxxxxxxx> The attribute cache for a file was not being cleared when a file is opened with O_TRUNC. If the filesystem's open operation truncates the file ("atomic_o_trunc" feature flag is set) then the kernel should invalidate the cached st_mtime and st_ctime attributes. Also i_size should be explicitly be set to zero as it is used sometimes without refreshing the cache. Signed-off-by: Ken Sumrall <ksumrall@xxxxxxxxxxx> Cc: Anfei <anfei.zhou@xxxxxxxxx> Cc: "Anand V.
