Konstantin Khlebnikov 9651e6b2e2 ext4: handle the rest of ext4_mb_load_buddy() ENOMEM errors ... I've got another report about breaking ext4 by ENOMEM error returned from ext4_mb_load_buddy() caused by memory shortage in memory cgroup. This time inside ext4_discard_preallocations(). This patch replaces ext4_error() with ext4_warning() where errors returned from ext4_mb_load_buddy() are not fatal and handled by caller: * ext4_mb_discard_group_preallocations() - called before generating ENOSPC, we'll try to discard other group or return ENOSPC into user-space. * ext4_trim_all_free() - just stop trimming and return ENOMEM from ioctl. Some callers cannot handle errors, thus __GFP_NOFAIL is used for them: * ext4_discard_preallocations() * ext4_mb_discard_lg_preallocations() Fixes: adb7ef600c ("ext4: use __GFP_NOFAIL in ext4_free_blocks()") Signed-off-by: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> Signed-off-by: Theodore Ts'o <tytso@mit.edu>		2017-05-21 22:35:23 -04:00
