mainline-inclusion from mainline-v5.11-rc4 commit a1a7d05a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4KIAO CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a1a7d05a05765eec042942a5c360e909c0dd0131 ------------------------------------------------- If a fs modification (creation, file write, reflink, etc.) is unable to reserve enough space to handle the modification, try clearing whatever space the filesystem might have been hanging onto in the hopes of speeding up the filesystem. The flushing behavior will become particularly important when we add deferred inode inactivation because that will increase the amount of space that isn't actively tied to user data.
