Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
struct rw_semaphore * | sem |
65 | Return atomic_long_read( & count) != 0 |
Name | Describe |
---|---|
populate_vma_page_range | populate_vma_page_range() - populate a range of pages in the vma |
zap_pud_range | |
anon_vma_free | |
wait_sb_inodes | The @s_sync_lock is used to serialise concurrent sync operations* to avoid lock contention problems with concurrent wait_sb_inodes() calls.* Concurrent callers will block on the s_sync_lock rather than doing contending* walks |
__writeback_inodes_sb_nr | |
sync_inodes_sb | sync_inodes_sb - sync sb inode pages*@sb: the superblock* This function writes and waits on any dirty inode belonging to this* super_block. |
sync_filesystem | Write out and wait upon all dirty data associated with this* superblock. Filesystem data as well as the underlying block* device. Takes the superblock lock. |
userfaultfd_huge_must_wait | Same functionality as userfaultfd_must_wait below with modifications for* hugepmd ranges. |
userfaultfd_must_wait | Verify the pagetables are still not ok after having reigstered into* the fault_pending_wqh to avoid userland having to UFFDIO_WAKE any* userfault that has already been resolved, if userfaultfd_read and* UFFDIO_COPY|ZEROPAGE are being run simultaneously on |
handle_userfault | The locking rules involved in returning VM_FAULT_RETRY depending on* FAULT_FLAG_ALLOW_RETRY, FAULT_FLAG_RETRY_NOWAIT and* FAULT_FLAG_KILLABLE are not straightforward |
dquot_scan_active | Call callback for every active dquot on given filesystem |
dquot_writeback_dquots | Write all dquot structures to quota files |
