https://bugzilla.kernel.org/show_bug.cgi?id=201685 --- Comment #93 from Guenter Roeck (linux@xxxxxxxxxxxx) --- Most of the ext4 patches in v4.19 have been backported to v4.18.y. Since v4.18.20 is reported to be stable, it is quite likely that the problem lies with one or more of the patches which have _not_ been backported. This would be one of the following patches. ext4: close race between direct IO and ext4_break_layouts() ext4: add nonstring annotations to ext4.h ext4: readpages() should submit IO as read-ahead dax: remove VM_MIXEDMAP for fsdax and device dax ext4: remove unneeded variable "err" in ext4_mb_release_inode_pa() ext4: improve code readability in ext4_iget() ext4: handle layout changes to pinned DAX mappings ext4: use swap macro in mext_page_double_lock ext4: check allocation failure when duplicating "data" in ext4_remount() ext4: fix warning message in ext4_enable_quotas() ext4: super: extend timestamps to 40 bits ext4: use timespec64 for all inode times ext4: use ktime_get_real_seconds for i_dtime ext4: use 64-bit timestamps for mmp_time block: Define and use STAT_READ and STAT_WRITE -- You are receiving this mail because: You are watching the assignee of the bug.
