From: Darrick J. Wong Date: Mon, 22 Jun 2015 01:10:51 +0000 (-0400) Subject: ext4: don't retry file block mapping on bigalloc fs with non-extent file X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=292db1bc6c105d86111e858859456bcb11f90f91;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ext4: don't retry file block mapping on bigalloc fs with non-extent file ext4 isn't willing to map clusters to a non-extent file. Don't signal this with an out of space error, since the FS will retry the allocation (which didn't fail) forever. Instead, return EUCLEAN so that the operation will fail immediately all the way back to userspace. (The fix is either to run e2fsck -E bmap2extent, or to chattr +e the file.)
