Subject: [PATCH] fs: fuse: Add replacment for CMA pages into the LRU cache
|
||
|
|
|
||
|
|
CMA pages are currently replaced in the FUSE file system since
|
||
|
|
FUSE may hold on to CMA pages for a long time, preventing migration.
|
||
|
|
The replacement page is added to the file cache but not the LRU
|
||
|
|
cache. This may prevent the page from being properly aged and dropped,
|
||
|
|
creating poor performance under tight memory condition. Fix this by
|
||
|
|
adding the new page to the LRU cache after creation.
|
||
