2016-02-03Suspend/resume culling based on recently released file/block countsnext-cullDavid Howells3-79/+223
Newer kernels include the counts of objects and blocks unpinned since last the status was read over the control device fd. The unpinning is usually through relinquishment by the netfs. If these fields are present, extract them and use them to work out whether there can be anything to cull. The fields are reset when read and POLLIN is signalled when the file counter is increased from 0. If there is nothing new to cull, scanning to build a cull table is suspended until more stuff is available. If the new fields are present, work on that basis - otherwise we sleep for 30s and try again. The thresholds at which culling should be resumed can be set by adding: resume_thresholds <block> <file> to the config file. The cull scan is retried when sufficient cumulative unpinning has happened that either threshold is exceeded. The block threshold watches the cumulative i_blocks for unpinned cache inodes and the file threshold watches the number of cache inodes unpinned. If either is "-" then that threshold is disabled. The default is 5 files and no block threshold. Further: (*) Some of the variable names are changed to be more obvious as to what they do. (*) If time-based culling is used, then SIGALRM must be blocked between the did-it-happen check and the call to poll. SIGINT, SIGTERM and SIGIO are already so blocked. (*) All the decision making logic is moved into the cachefilesd() function rather than being spread out.

2016-01-25cachefilesd can spin when disk space is short.NeilBrown1-3/+6
When cachefilesd finds that it needs to cull, but that culling doesn't achieve anything, it sets an alarm to wake it in 30 seconds to try again. But as read_cache_state() will detect that culling is still needed, it will immediately try again anyway. This results in 100% cpu usage of no value. This patch causes culling to be blocked until the 30 second alarm goes off. It also changes the test to decide whether to enter poll() after blocking signals to test exactly those values that might be changed by a signal. Testing these is important, testing anything else is pointless.

Provide an option to suppress cachefilesd culling. This prevents the daemon from using up resources scanning the cache.

2010-02-22cachefilesd historical revision 0.9v0.9David Howells2-27/+47
The cachefiles module no longer accepts directory fds on cull and inuse commands, but rather uses current working directory. Use stat64/fstatat64 to avoid EOVERFLOW errors from the kernel on large files.
2010-02-22cachefilesd historical revision 0.8v0.8David Howells12-87/+663
Made cachefilesd ask the kernel whether cullable objects are in use and omit them from the cull table if they are. Made the size of cachefilesd's culling tables configurable. Updated the manual pages. Documented SELinux interaction. Include SELinux policy for cachefilesd. Fixed typo that was causing the howto.txt not to be installed. Use /dev/cachefiles if it present in preference to /proc/fs/cachefiles. Use poll rather than SIGURG on /dev/cachefilesd.
2010-02-22cachefilesd historical revision 0.7v0.7David Howells3-4/+273
