523d27cd - afs: Convert afs to use the new fscache API

Thu, 06 Feb 2020 14:22:21 +0000

afs: Convert afs to use the new fscache APIChange the afs filesystem to support the new afs driver.The following changes have been made: (1) The fscache_netfs struct is no more, and there's no need to register the filesystem as a whole. There's also no longer a cell cookie. (2) The volume cookie is now an fscache_volume cookie, allocated with fscache_acquire_volume(). This function takes three parameters: a string representing the "volume" in the index, a string naming the cache to use (or NULL) and a u64 that conveys coherency metadata for the volume. For afs, I've made it render the volume name string as: "afs,," and the coherency data is currently 0. (3) The fscache_cookie_def is no more and needed information is passed directly to fscache_acquire_cookie(). The cache no longer calls back into the filesystem, but rather metadata changes are indicated at other times. fscache_acquire_cookie() is passed the same keying and coherency information as before, except that these are now stored in big endian form instead of cpu endian. This makes the cache more copyable. (4) fscache_use_cookie() and fscache_unuse_cookie() are called when a file is opened or closed to prevent a cache file from being culled and to keep resources to hand that are needed to do I/O. fscache_use_cookie() is given an indication if the cache is likely to be modified locally (e.g. the file is open for writing). fscache_unuse_cookie() is given a coherency update if we had the file open for writing and will update that. (5) fscache_invalidate() is now given uptodate auxiliary data and a file size. It can also take a flag to indicate if this was due to a DIO write. This is wrapped into afs_fscache_invalidate() now for convenience. (6) fscache_resize() now gets called from the finalisation of afs_setattr(), and afs_setattr() does use/unuse of the cookie around the call to support this. (7) fscache_note_page_release() is called from afs_release_page(). (8) Use a killable wait in nfs_vm_page_mkwrite() when waiting for PG_fscache to be cleared.Render the parts of the cookie key for an afs inode cookie as big endian.Changes=======ver #2: - Use gfpflags_allow_blocking() rather than using flag directly. - fscache_acquire_volume() now returns errors.Signed-off-by: David Howells Acked-by: Jeff Layton Tested-by: kafs-testing@auristor.comcc: Marc Dionne cc: linux-afs@lists.infradead.orgcc: linux-cachefs@redhat.comLink: https://lore.kernel.org/r/163819661382.215744.1485608824741611837.stgit@warthog.procyon.org.uk/ # v1Link: https://lore.kernel.org/r/163906970002.143852.17678518584089878259.stgit@warthog.procyon.org.uk/ # v2Link: https://lore.kernel.org/r/163967174665.1823006.1301789965454084220.stgit@warthog.procyon.org.uk/ # v3Link: https://lore.kernel.org/r/164021568841.640689.6684240152253400380.stgit@warthog.procyon.org.uk/ # v4 List of files: /linux-6.15/fs/afs/Kconfig

5cbf0398 - afs: Use new netfs lib read helper API

Thu, 06 Feb 2020 14:22:29 +0000

afs: Use new netfs lib read helper APIMake AFS use the new netfs read helpers to implement the VM readoperations: - afs_readpage() now hands off responsibility to netfs_readpage(). - afs_readpages() is gone and replaced with afs_readahead(). - afs_readahead() just hands off responsibility to netfs_readahead().These make use of the cache if a cookie is supplied, otherwise just callthe ->issue_op() method a sufficient number of times to complete the entirerequest.Changes:v5:- Use proper wait function for PG_fscache in afs_page_mkwrite()[1].- Use killable wait for PG_writeback in afs_page_mkwrite()[1].v4:- Folded in error handling fixes to afs_req_issue_op().- Added flag to netfs_subreq_terminated() to indicate that the caller may have been running async and stuff that might sleep needs punting to a workqueue.Signed-off-by: David Howells Tested-By: Marc Dionne cc: linux-afs@lists.infradead.orgcc: linux-cachefs@redhat.comcc: linux-fsdevel@vger.kernel.orgLink: https://lore.kernel.org/r/2499407.1616505440@warthog.procyon.org.uk [1]Link: https://lore.kernel.org/r/160588542733.3465195.7526541422073350302.stgit@warthog.procyon.org.uk/ # rfcLink: https://lore.kernel.org/r/161118158436.1232039.3884845981224091996.stgit@warthog.procyon.org.uk/ # rfcLink: https://lore.kernel.org/r/161161053540.2537118.14904446369309535330.stgit@warthog.procyon.org.uk/ # v2Link: https://lore.kernel.org/r/161340418739.1303470.5908092911600241280.stgit@warthog.procyon.org.uk/ # v3Link: https://lore.kernel.org/r/161539561926.286939.5729036262354802339.stgit@warthog.procyon.org.uk/ # v4Link: https://lore.kernel.org/r/161653817977.2770958.17696456811587237197.stgit@warthog.procyon.org.uk/ # v5Link: https://lore.kernel.org/r/161789101258.6155.3879271028895121537.stgit@warthog.procyon.org.uk/ # v6 List of files: /linux-6.15/fs/afs/Kconfig
